1. Ask modulation : "Amplitude shift keying" is also known as "amplitude keying", or "open key Control" (on-off keying), so it is also recorded as Ook signal. Ask is a relatively simple method of modulation. The amplitude shift keying (ASK) is equivalent to the amplitude modulation in the analog signal, except that the binary digital is multiplied by the carrier signal. Amplitude shift is the frequency, phase as a constant, and the amplitude as a vari

GSM system is the world's most widely-covered second-generation wireless network, it uses TDMA (time division multiple Access) approach, that is, in a carrier channel, at the same interval at the same intervals into a fixed cycle of several time slots, each time slot carries a business user information and necessary signaling. In this way, a carrier channel is occupied by a number of users in chronological

On Saturday, I went to shangdiqi Street, a company. After talking with others, I found that this template class has been in use for a long time. When I came back, I thought I should add a feature that the template class always needed. Is to support information carriers. That is to say, in the custom tag parsing function, we can ob

I. Problem Description The existence of Network Address Translation and firewall (NAT/FW) blocks multiple multimedia communication protocols, including H.323, because the NAT device only translates the IP address/port of the message header, the message's IP header is inconsistent with the address/port information in the message's Net Load. As a result, the Message Receiver cannot correctly respond to the message, and the media channels of both parties cannot be properly established. In H.323 mul
